I've created a site similar to block explorer with a couple of improvements:
- Includes orphaned blocks which can be used to track possible double spends
- Estimates the actual volume of BTC transacted (not just BTC sent)
The site can be found at:

Is the site down? As of 3:38pm PST, this appears to be the case. Wanted to ask a question about the calculation method on transactional volume.
